This is a horrid situation for you and one lots of people have been experiencing over lockdown. You have 3 choices: 1) Treat the source: continue to try to build neighbour relations so that their behaviour changes. It sounds like you have your opinions of them already which is understandable, but they are a family with young children who have most likely been bouncing off the walls same as everyone else during all the fluffery of the last 2 years. Not being disrupted by your neighbours when you live in a victorian conversion is, as I have experienced as well, not an option! If you can demonstrate that you understand and empathise with their situation, maybe they will act likewise. 2) Treat the path of the noise (improving the sound insulation): You say you are not currently in a financial position to do this but there are options which might take the edge off if you ever are. Even then, if you are only able to treat the floor-side of your floor (i.e. not the ceiling below) then you will probably only make the situation a bit better but probably won't fully remedy the situation. Noise will also be travelling up the walls, old chimneys and lots of other paths. They are unlikely ever to share the cost with you. 3) Treat the receiver: Yes, ear plugs. Yes, white noise machine. Unfortunately once you have tuned into it you are unlikely to be able to tap into the reserves of tolerance or empathy that you might be able to conjure up in other areas of your life. This is your home, and it feels like it is under siege. Without one of the above options being viable I think the best you can hope for is that the enemy at the gate gets tired or ages and goes away... Best of luck!
